Quoting from Documentation/networking/packet_mmap.txt:
fd= socket(PF_PACKET, mode, htons(ETH_P_ALL))
where mode is SOCK_RAW for the raw interface were link level
information can be captured or SOCK_DGRAM for the cooked
interface where link level information capture is not
supported and a link level pseudo-header is provided
by the kernel.
So not including the link layer header for SOCK_DGRAM sockets
seems to be the intended behaviour.
